  • Thermistors NTC/PTC/LPTC/PPTC
    Thermistor as a thermal sensitive passive component it shows negative or positive resistance effect with changing of subject temperature.  With its predictable and accuracy sensing performance,  it is widely used in circuit performing as measurement control or protect functions
  • Level/Temp/Reed Switch Sensor
    With the interaction between matching parameter reed and magnet, Focusens design and produce proximate switch as both vertical and horizontal types. Our switch sensor give control liquid level,proximate position with combination of temperature control as electrical switch for extensive applications.
  • Temperature Sensor
    Focusens concentrate on components solution for temperature, humidity, level and position sensing and control.  We design develop and produce sensors for 5 major applications : Household, automobile both fueled and EV energy,medical, IoT and industry Our sensor covers full line of thermistors,PT RTDs, Thermocouples,as well as Digital types like DS18B20 ,LM35 ,TMP117, DS2431 etc.for temperature sensing. We also flexible custom humidity and reed base magnetic level and position switch sensors for extensitive application conditions. 
  • Thermal Fuse/Thermal Protector
    Thermal Fuse or TCO thermal cut off are non-resettable electronic compontent, it will melt or broke out when circuit is over hot. The thermal protector however is auto or manually resetable protective devices cutting or connecting circuit under desired conditions.
  • Temperature/Humidity Transmitter
    We Adopt Standard Manufacturing Management.  Quality Control According to ISO 9001:2015 System and On site Management Strictly Conducted Under 6S System.  All our products are ROHS and REACH compliance.
